1973-05-19 Antonio Cervantes w rsc 5 (15) Alfonso Frazer, New City Gym, Panama City, Panama - WBA. Referee: Luis Sulbaran. Frazer (137½), yet another former champion looking to regain his old title, made a good start when carrying the fight to Cervantes (139½), but by the second round he was really up against it as the current titleholder started to pick him apart. By the third, with Cervantes warming to the task Frazer was floored three times before getting on his bike in order to survive. Floored again in the fourth and then early in the fifth Frazer had no defence against the power-packed punches coming his way, and after being decked twice more the referee came to his rescue at 1.38 of the session.
